4Beit known tl/at l, SAMUEL WILLIAMS,

va citizen'of the'iUnited States, and a resident of` Toledo, the county of Lucas and 4'State "of'Ohiog have invented a certain new Eand useful*Automobile-Radiator; and I do herebydeclare the following to be a full, clear,l and exact' description of the invention, such as will 'enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom- 'panying drawings, and to the characters of reference marked thereon, which form a part of this' specification.

'Thisfinvention' relates to radiators, and particularly to those of the type adapted Yfor use onva'utor'nobiles in connection with the water cooling systems of the internal combustion engines thereof.

- The objectof'my invention is the provision-of an'il'nproved radiator of the class described, which is simple and inexpensive in: its construction' 1and has each tier or sectionof'fair cells thereof formed by a single s trip or sheet" of y metal, whereby the assemblingvof-'the parts of a radiator is materially facilitated and simplified and the makingof vrepairs rendered easier.

The invention is fully described in the following `spec'ic'ation, and while, in its broaderaspect,it iscapable of embodiment in numerous'forms, a preferred embodiment thereof `is illustrated in the 'accompanying drawings, in '-whichy'Figurei lisisy afrontelevation of a radiator larged perspectivefview of one of the air cell sections I'ofthe radiator, with a part broken away. iE-igis *an* edge view of two air cell sections pla'ceditogether to forma water circulating passage therebetween, and Fig. 4 is a sectiononithe'line 4 4: in Fig. 3.

The radiator" embodying my invention is composed.v offaplurality of air cell sections- A, which are secured 'together in side Aabutand lowerendsoft-the water `passa-ges be#v tween the cell sections A, respectively l com- .mu'nicate, asis? well :understood in theart.

Each cell section A. forms a plurality of horizontally disposed cells a, which eX tend from front to rear of the radiator. Each cell section A is coinposed of a single sheet or strip of sheet metal, such metal being so bent as to form the successive cells of a section in superimposed relation. Beginni'ng,` in the present instance, at the upper end of a cell section., the metal sheet or v strip forming the same is bent in inverted4 f U-shape to forni the leg portions l and 2 Vand crown portion 3, with the leg portion l slightly longer than the depth of the first cell a so as to lap the adjacent edge ofthe next subjacent cell a, as shown at et. The

leg 2 is of sufficient length to entend down beyond the adjacent side of the second cell and to lap for a short distance the respecl tive upper edge of the third cell in order.

The metal is then again formed in U-shape with the right-hand leg 5 thereof. or that adjacentto the'leg 2, ,doubledback within said leg in close side abutting relation thereto, and with its otheror left-hand leg 6 eX- tendlng down below the adjacent upper edge of the fourth cell in order, while the crown portion 7 of Asuch U-shaped part forms the bottoni and top, respectively, of the upper and second cells ofthe section.; The

sheet is then again formedgin U-shape, with, f

its left-hand leg doubling back against the inner side of the leg` 6 for substantially,y

half the length thereof, and with its other lleg, which is the long' leg, extending down 1n lapping relation tothe adjacent upper edge of the fifth cellin order, and this operation is repeated as manytimes as-there.

arey cells in the section until the last. sec-".1

at its end against the g opposite doubledy I :back wallportion ofthe cell, asshown at the bottom of Fig. 2'. In other wor`ds,*a radiator section A comprises a 'plufrzulityfof4 i integrally connected U-shapedparts which are nested 1n successive order one within another, with their 'crown portions equidistantly spaced in'accordance with they desiredv depthof the cells, and with one leg of eafch U-shaped part lengthened with respect to the other leg and integrally connected at its free end to the free end of the short leg of the U-shaped part nested therein, the long legs of the successive U-shaped parts alternating with respect to the sides of the seetion. The short leg of each U-shaped part laps for a short distance the inner end portion of the long leg of the next U-shaped part in order, or the one nested therein, and is fixedly secured thereto in a watertight manner by'solder, or other suitable means.

It is evident with this construction of radiator section that it is formed of a single strip of sheet metal and that alternate side walls of the successive cells are of double thickness by reason of the doubling back of the metal at such sides.

The sections A have their sides inwardly bowed or broadened at their outer ends so that the broadened end portions of adjoining sections abpt and space the intermediate vao portions of the sections to form a vertical water space or passage 8 therebetween. Then the sections A forming a radiator are secured together in rear sides o f the block are dipped in solder, or otherwise suitably treated to secure the sections together and to close any spaces occurring lbetween the abutting edgeportions of the sections to render the passages 8 water tight at such edges.

dVhen the sections are assembled -it is preferable, but not necessary, to place the the sections doublethicl{ness or reinforced Side wall of the cells in each section opposite the singlethickness side walls of the cells of the adjoining sectiomas shown in Figs. 3 and et.'

It is also preferablel in assembling to have the leg portlons of the respective U parts of extending downward instead of upward, thereby' lessening the tendency of leakage through the seams 9 of the sections. I wish it understood that my invention is not limited to any specific construction, arrangement or forni of the parts, as it is capable of numerous moditications without departing from the spirit of the claims.

Having thus described my invention, what I cla-im as new, anddesire to secure by Lets ters Patent, isil 1. In a radiator, a plurality of U-shaped sheet metal parts nested together to form a lplurality of cells and having their legs extending -in the same direction, the crown portions of said parts being spaced and the legs of each part beingsecured to the sides` of the part nested therein. y

2. In a radiator, a plurality of U-shaped sheet metal parts nested together to'form a plurality of cells, the crown portions of said parts being spaced, and each part having one leg integrally connected to t-he leg of the next part in order.

3. In a radiator, a cell section having a block forni lthe front and 4. In a radiator, a plurality ot' U-shaped section and with alternate sheet metal parts nested together to forni a plurality of cells vertically of the radiator, the crown portions of said parts being spaced, and the legs of each part being of unequal length, with the long leg integrally connected to the short leg in order.

5. In a radiator, a plurality of U-shaped sheet metal 'parts nestedtogether to form a plurality of cells, the crown portions of said parts being spaced, being of unequal length, with the long legs thereof alternating with respect to the sides of the section and each attached to and cooperating'with the short leg of the next secof the next part and the legs of each part tion in order to form the side wall of a cell.

(3. In a radiator, a plurality of U-shapcd sheet metal parts nested together to forni a pluraliQvof cells, the crown portions of said parts being spaced, and the legs of each part being of unequal length, with the long legs ofthe several parts alternating with respect to the section sides and integrally connected at their vouter ends to the outer ends of the short legs of the parts next in order, the connected ends of the long and short legs of adjoining partsl being fixed to the adjacent'edge of the crown portion of an adjoining section.

7. In a radiator, a plurality of U-shapcd sheet metal parts nested together to forni a plurality of cells, the crown portions oi said parts being spaced, and the leg portions thereof being alternately lengthened, with the long leg of 011e part lapping the short leg of the next part 1n order and integrally connected to the end of said short leg, with the adjacent end portions of said legs lapping the end ofthe long leg=of the third part in order and forming a close joint therewith.

8. Ina radiator, a plurality of sections disposed side by side and forming a water passage therebetween, each of said sections having a pluralityof U-shaped parts forining successive cells, with the crown portions of said parts spaced, and with the legs thereof alternately lengthened to extend down at the outer side of the short leg of the next part in order and attached at its end to the n end' of the short leg which it laps and to the end of the 'third U-shaped part in order.
